Answer:

x = 1 and vertex = (1, - 7 )

Step-by-step explanation:

Given a quadratic function in standard form

y = ax² + bx + c ( a ≠ 0 )

The the equation of the axis of symmetry which is also the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = 4x² - 8x - 3 ← is in standard form

with a = 4, b = - 8 , then

x = - [tex]\frac{-8}{8}[/tex] = 1

That is equation of axis of symmetry is x = 1

Substitute x = 1 into the function for y- coordinate of vertex

y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7

vertex = (1, - 7 )

Answer:

[tex]\dfrac{5}{7}[/tex]

Step-by-step explanation:

Given numbers are :

0.30 cm and 0.42 cm

We need to find the ratio of the above whole numbers.

Taking 0.3 cm on the numerator and 0.42 cm on the denominator. So,

[tex]\dfrac{0.3}{0.42}=\dfrac{\dfrac{3}{10}}{\dfrac{42}{100}}\\\\=\dfrac{3}{10}\times \dfrac{100}{42}\\\\=\dfrac{10\times 3}{42}\\\\=\dfrac{10}{14}\\\\=\dfrac{5}{7}[/tex]

So, the required fraction is equal to [tex]\dfrac{5}{7}[/tex].

Answer:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

Step-by-step explanation:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

since each interval contains equal number of values lets divide the data into 6 groups i.e.  frequency in the third group = 30 /6 = 5

hence we can say that the number of intervals used to test the hypothesis is 5

Answer:

  a) 1

  b) 3

  c) {{3, 6, 7}, {8, 12, 14}, {9, 10, 17}, {11, 13, 16}, {15, 18, 19}

  d) cannot do. The numbers cannot add up.

Step-by-step explanation:

a) The minimum difference between rod lengths is 1. A unit-length rod cannot be used, because the sum of that and another length cannot exceed a third length. 1 + 2 = 3; is not greater than 3.

b) The 3 possible pairs of triangles are

  {2, 3, 4}, {5, 6, 7}

  {2, 4, 5}, {3, 6, 7}

  {2, 6, 7}, {3, 4, 5}

__

c) There are numerous ways to make 5 triangles having an even perimeter. One is shown above. Several more are ...

  {5, 12, 15}, {7, 17, 18}, {8, 10, 16}, {9, 13, 20}, {11, 14, 19}

  {5, 15, 16}, {6, 9, 13}, {7, 14, 19}, {8, 11, 17}, {10, 12, 18}

  {3, 9, 10}, {5, 15, 16}, {7, 13, 18}, {8, 11, 17}, {12, 14, 20}

  {4, 9, 11}, {5, 12, 13}, {7, 18, 19}, {8, 15, 17}, {10, 16, 20}

  {5, 12, 13}, {7, 18, 19}, {8, 11, 15}, {9, 17, 20}, {10, 14, 16}

__

d) No such set exists.

The sum of the 19 rod lengths is 209. Even if we throw out the rod of length 20 (to make a set of 18 rods), the perimeter must be at least 2(19)+1 = 39. Six triangles with that perimeter would require a total rod length of 6(3) = 234. The total length of rods is insufficient to make the required triangles.

Step-by-step explanation:

radius is half of a diameter so that means you need to multiply 72 times 2

Answer:

88 half gallons

Step-by-step explanation:

We can solve this problem by creating an equation. First we will need a variable. Since we are trying to find how many half gallons the store bought, that will be what our variable represents.

Let g = the number of half gallons

Since the store bought milk for $2.60 per half gallon, the amount of money they spent will be 2.6g.

The remaining milk is sold for $4.08 per half gallon. Remember, the store lost 15 half gallons so the number of gallons is currently g-15. This means that to find the amount of profit they made, we use 4.08(g-15).

We already know that the profit is $69.04, so we can make this into an equation.

This profit is the amount of money made minus the cost.

4.08(g-15) - 2.6g = 69.04

We can begin to solve this by simplifying the left side.

4.08(g-15) - 2.6g

4.08g - 61.2 - 2.6g

1.48g - 61.2

This makes our new equation:

1.48g - 61.2 = 69.04

We can begin to isolate our variable, g, by adding 61.2 to both sides.

1.48g = 130.24

Then we divide both sides by 1.48.

g = 88

Answer:

1 hr 2 min 30 secs

Step-by-step explanation:

Assume Propagation speed = 100 km/hr

number of cars = 5

distance between booths = 50 km

Total distance = 100 km

take taken to serve each car = 12 secs

Determine the end to end delay

first calculate the propagation delay = Total distance / propagation speed

                                                             = 100 / 100 = 1  hr

next calculate : Time taken to serve 5 cars in each Tollbooth

= 5 * 12 secs = 60 secs

Next calculate : transmission delay ( time taken by three tollbooth to reach 5 cars )

= 60 secs * 3 = 180 secs = 2 min 30 secs

therefore end-end delay

= propagation delay + transmission delay

= 1 hr 2 min 30 secs

Step-by-step explanation:

-16/4=-4

g-4

The solution after simplifying the variable expression by evaluating its numerical part is (g - 4).

Given that,

The expression is,

[tex]g - \dfrac{16}{4}[/tex]

Used the concept of expression by combining the like terms.

Now, simplify each term as,

[tex]g - \dfrac{16}{4}[/tex]

Here, [tex]\dfrac{16}{4} = 4[/tex]

So, we get;

[tex]= g - 4[/tex]

Therefore, the solution is (g - 4).

Use the theta or x in place of the usual angle. the lengths are adjacent and hypotenuse (a/h) so you use cosine. cos(x)=35/38 or cos(θ)=35/38

Answer:

1 out of 8, or 12.5 percent.

Step-by-step explanation:

There were 2 red skittles out of 16 total skittles, and then we divide the numbers by 2, then we get 1 out of 8. Converting it into a percentage, there is a 12.5% chance of pulling out a red skittle.
